Question

which figure shows the construction of an angle bisector?

Explanation:

An angle bisector construction requires that the arcs drawn from the angle's vertex intersect both sides, then arcs from those intersection points meet inside the angle, and the line from the vertex to that meeting point splits the angle into two equal parts. Figure A shows the correct markings where the constructed line divides the original angle into two congruent smaller angles, matching the angle bisector construction steps.

Answer:

A. <The figure with the constructed line splitting the angle into two equal parts, marked with congruent arc segments on both sides of the bisector>
